Some days ago have problem, Search Crawl and SharePoint Web services, just dont Work, what come to my mind..."Anonymous access on IIS was checked", go see and was Uncheck,
Hummm.... after this i go to event Viewer and saw:
"Context: Application '[SharedServicesname]', Catalog 'Portal_Content'
Access is denied. Check that the Default Content Access Account has access to this content, or add a crawl rule to crawl this content. (0x80041205); [Site]"
Ok another security problem, But where??? everythig was right and working "hate when this happen", i think "Host name problem" a litle search and i find a article that give then answer, "specify the host names that are mapped to the loopback address and can connect to Web sites on your computer", yep that was my problem....
